Problems solved by technology

[0009] Aiming at the problems of poor dispersibility, easy agglomeration, weak bonding, easy leakage of phase change materials, and poor thermal insulation effect of debugging in diatomite temperature-regulating wallpapers that are widely used at present, the present invention proposes a long-term thermal insulation and temperature-regulating wallpaper. The diatomite wallpaper and its preparation method effectively improve the moisturizing and temperature-regulating effect of the diatomite temperature-regulating wallpaper. At the same time, the diatomite is evenly dispersed, and the product performance is good and the effect is long-lasting

Abstract

The invention provides diatomite wallpaper with long-acting heat preservation and temperature adjustment and a preparation method. Diatomite and a phase-change material are heated and stirred to moisten the phase-change material, and the diatomite is coated with the phase-change material; pressure is increased in the ultrasonic environment, the diatomite phase-change material is obtained after cooling and discharging, and the diatomite phase-change material is added into methyl methacrylate; a microporous composite phase-change material is prepared by radiation under the action of an initiatorand a blowing agent, and coated between two layers of polyvinyl chloride films, and diatomite composite wallpaper is prepared after hot-pressing. The composite phase-change material is coated by polymer, and is subjected to the hot-pressing to be firmly fixed on a base material, so that the problem of leakage of the phase-change material is solved, and the diatomite has good dispersity, good ability of temperature adjustment and humidity adjustment and long-acting heat preservation effect; and the whole preparation process is simple, easy operation is achieved, a raw material is easy to obtain, the production cost is low, and the diatomite wallpaper with the long-acting heat preservation and temperature adjustment can be industrialized and popularized.
